RabbitMQ開啟SSL與SpringBoot連線測試

東北小狐狸發表於2022-01-07

楔子

近期公司程式被安全掃描出 遠端主機允許明文身份驗證 中風險漏洞,查了下修復方案,RabbitMQ官方提供了SSL連線方式,而且 SpringBoot AMQP 也支援 SSL 連線。以下將配置RabbitMQ開啟SSL 並使用 SpringBoot Demo 測試連線。

PS : 寫文章時此配置還未安全掃描複測,如果測試通過,本人將更新此文章狀態為驗證通過。

配置 RabbitMQ 開啟 SSL

本文基於 CentOS 7 + Git + OpenSSL + yum 安裝的 RabbitMQ,需要讀者提交安裝好。其他方式也可變通參考本文。

生成證照

#克隆生成證照的倉庫到當前目錄
git clone --depth 1 https://github.com/Berico-Technologies/CMF-AMQP-Configuration.git
cd CMF-AMQP-Configuration/ssl
#生成ca證照,“MyRabbitMQCA”為自定義名稱,名稱任意。在當前目錄下生成ca目錄
sh setup_ca.sh MyRabbitMQCA
#生成服務端證照,第一個引數是服務端證照字首,第二個引數是密碼。密碼任意,在當前目錄下生成server目錄
sh make_server_cert.sh rabbitmq-server 123456
#生成客戶端證照,第一個引數是客戶端證照字首,第二個引數是密碼。密碼任意,在當前目錄下生成client目錄
sh create_client_cert.sh rabbitmq-client 654321

配置 RabbitMQ 服務端的證照如下:

ca/cacert.pem #CA證照
server/rabbitmq-server.cert.pem #服務端公鑰
server/rabbitmq-server.key.pem  #服務端私鑰

使用 RabbitMQ 服務端公鑰證照生成 JKS 證照

# -alias後為別稱,-file後是服務端公鑰位置,-keystore後是輸出JSK證照位置,此處相對路徑
keytool -import -alias rabbitmq-server \
  -file server/rabbitmq-server.cert.pem \
  -keystore rabbitmqTrustStore -storepass changeit
#輸入y回車

配置 RabbitMQ 客戶端的證照如下:

client/rabbitmq-client.keycert.p12 #PKCS12證照,包含客戶端所需公私鑰及中間證照
rabbitmqTrustStore #服務端JKS格式公鑰

預設 RabbitMQ 配置目錄在 /etc/rabbitmq,我們建立個證照目錄存放服務端證照

mkdir -p /etc/rabbitmq/ssl
#複製服務端必要證照
cp ca/cacert.pem \
server/rabbitmq-server.cert.pem \
server/rabbitmq-server.key.pem /etc/rabbitmq/ssl/

修改 RabbitMQ 配置檔案

修改 RabbitMQ 配置檔案 /etc/rabbitmq/rabbitmq.config,此檔案預設不存在,需要手動建立

[{rabbit, [
    {ssl_listeners, [5671]},
    {ssl_options, [
        {cacertfile, "/etc/rabbitmq/ssl/cacert.pem"},
        {certfile,   "/etc/rabbitmq/ssl/rabbitmq-server.cert.pem"},
        {keyfile,    "/etc/rabbitmq/ssl/rabbitmq-server.key.pem"},
        {verify, verify_peer},
        {fail_if_no_peer_cert, true},
        {ciphers, [
            "ECDHE-ECDSA-AES256-GCM-SHA384","ECDHE-RSA-AES256-GCM-SHA384",
            "ECDHE-ECDSA-AES256-SHA384","ECDHE-RSA-AES256-SHA384",
            "ECDHE-ECDSA-DES-CBC3-SHA","ECDH-ECDSA-AES256-GCM-SHA384",
            "ECDH-RSA-AES256-GCM-SHA384","ECDH-ECDSA-AES256-SHA384",
            "ECDH-RSA-AES256-SHA384","DHE-DSS-AES256-GCM-SHA384",
            "DHE-DSS-AES256-SHA256","AES256-GCM-SHA384",
            "AES256-SHA256","ECDHE-ECDSA-AES128-GCM-SHA256",
            "ECDHE-RSA-AES128-GCM-SHA256","ECDHE-ECDSA-AES128-SHA256",
            "ECDHE-RSA-AES128-SHA256","ECDH-ECDSA-AES128-GCM-SHA256",
            "ECDH-RSA-AES128-GCM-SHA256","ECDH-ECDSA-AES128-SHA256",
            "ECDH-RSA-AES128-SHA256","DHE-DSS-AES128-GCM-SHA256",
            "DHE-DSS-AES128-SHA256","AES128-GCM-SHA256",
            "AES128-SHA256","ECDHE-ECDSA-AES256-SHA",
            "ECDHE-RSA-AES256-SHA","DHE-DSS-AES256-SHA",
            "ECDH-ECDSA-AES256-SHA","ECDH-RSA-AES256-SHA",
            "AES256-SHA","ECDHE-ECDSA-AES128-SHA",
            "ECDHE-RSA-AES128-SHA","DHE-DSS-AES128-SHA",
            "ECDH-ECDSA-AES128-SHA","ECDH-RSA-AES128-SHA","AES128-SHA"
        ]}
    ]}
]}].

主要配置項說明:

  • ssl_listeners 指定 SSL協議的埠號,官方文件 5671
  • ssl_options SSL 認證配置項
    • cacertfile CA 證照位置
    • certfile 公鑰證照位置
    • keyfile 金鑰證照位置
    • verify
      • verify_peer 客戶端與服務端互相傳送證照
      • verify_none 禁用證照交換與校驗
    • fail_if_no_peer_cert
      • true 不接受沒證照的客戶端連線
      • false 接受沒證照的客戶端連線
    • ciphers 加密器(這個翻譯不知道算不算對?)

重啟 RabbitMQ

#關閉
rabbitmqctl stop
#啟動
rabbitmq-server -detached

驗證開啟 SSL 是否成功

使用 Rabbitmq 自帶的診斷工具檢視埠監聽狀態及使用協議

#檢視監聽
rabbitmq-diagnostics listeners
#檢視支援的TLS版本
rabbitmq-diagnostics --silent tls_versions

使用 OpenSSL CLI 工具驗證證照是否有效

cd 生成證照的ssl目錄
#使用客戶端證照+CA證照連線RabbitMQ驗證。本處MQ與生成證照是同一主機,其他情況請自行考慮。
openssl s_client -connect localhost:5671 \
  -cert client/rabbitmq-client.cert.pem \
  -key client/rabbitmq-client.key.pem \
  -CAfile ca/cacert.pem

除了命令列檢視外,還可以通過管理介面檢視,不過只能確定開啟了 SSL 監聽,無法確認證照是否通過驗證。

編寫 SpringBoot 程式碼連線測試

程式碼結構

只是使用 start.spring.io 生成的 Maven 工程,依賴了 WEB 和 AMQP

啟動類 DemoApplication.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

RabbitMQ客戶端配置類 RabbitFanoutExchangeConfig.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class RabbitFanoutExchangeConfig {
    public static final String FANOUT_EXCHANGE = "fanout.exchange";
    public static final String FANOUT_QUEUE1 = "fanout.queue1";

    @Bean(name = FANOUT_EXCHANGE)
    public FanoutExchange fanoutExchange() {
        return new FanoutExchange(FANOUT_EXCHANGE, true, false);
    }


    @Bean(name = FANOUT_QUEUE1)
    public Queue fanoutQueue1() {
        return new Queue(FANOUT_QUEUE1, true, false, false);
    }
    
    @Bean
    public Binding bindingSimpleQueue1(@Qualifier(FANOUT_QUEUE1) Queue fanoutQueue1,
                                       @Qualifier(FANOUT_EXCHANGE) FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(fanoutQueue1).to(fanoutExchange);
    }
}

發訊息測試類 TestController.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.amqp.core.Message;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {
    @Autowired
    RabbitMQSenderService rabbitMQSenderService;
    
    @GetMapping("/test")
    public void sendMsg() {
        Message msg = new Message("hello world".getBytes());
        try {
            rabbitMQSenderService.send(RabbitFanoutExchangeConfig.FANOUT_EXCHANGE,
                    RabbitFanoutExchangeConfig.FANOUT_QUEUE1, msg);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

發訊息服務 RabbitMQSenderService.java

package com.hellxz.rabbitmq.ssl;

import java.util.UUID;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class RabbitMQSenderService {
    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void send(String exchange, String routingkey, Message message) {

        CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
        System.out.println("start send msg : " + message);
        rabbitTemplate.convertAndSend(exchange, routingkey, message, correlationId);
        System.out.println("end send msg : " + message);
    }
}

訊息接收者 RabbitMQReciver.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
class RabbitMQReciver {

    @RabbitListener(queues = RabbitFanoutExchangeConfig.FANOUT_QUEUE1)
    public void reciveLogAll(String msg) throws Exception {
        System.out.println("received msg:" + msg);
    }
}

配置檔案 application.properties

server.port=8085

#基礎配置請根據實際配置
spring.rabbitmq.host=192.168.56.104
#ssl協議埠
spring.rabbitmq.port=5671
spring.rabbitmq.username=admin
spring.rabbitmq.password=123456
spring.rabbitmq.virtual-host=/

#啟用rabbitmq客戶端SSL連線
spring.rabbitmq.ssl.enabled=true
#客戶端PKCS12證照及密碼
spring.rabbitmq.ssl.key-store=classpath:ssl/rabbitmq-client.keycert.p12
spring.rabbitmq.ssl.key-store-password=654321
#公鑰證照及型別
spring.rabbitmq.ssl.trust-store=classpath:ssl/rabbitmqTrustStore
spring.rabbitmq.ssl.trust-store-type=JKS
#不校驗主機名,預設開啟會導致連線失敗
spring.rabbitmq.ssl.verify-hostname=false

src/main/resources 下建立 ssl 目錄,將 客戶端證照和服務端JKS公鑰複製到 ssl 目錄中。

執行程式碼驗證

執行 DemoApplication.java,檢視控制檯是否有報錯:

如圖,提示建立連線成功,說明已經連線成功了。

我們再呼叫 TestController.java 中定義的 /test 介面

訊息傳送與消費成功。
